/**
 * This demonstrates available character encodings. Escpos-php accepts UTF-8,
 * and converts this to lower-level data to the printer. This is a complex area, so be
 * prepared to code a model-specific hack ('CapabilityProfile') for your printer.
 *
 * If you run into trouble, please file an issue on GitHub, including at a minimum:
 * - A UTF-8 test string in the language you're working in, and
 * - A test print or link to a technical document which lists the available
 *      code pages ('character code tables') for your printer.
 *
 * The DefaultCapabilityProfile works for Espson-branded printers. For other models, you
 * must use/create a PrinterCapabilityProfile for your printer containing a list of code
 * page numbers for your printer- otherwise you will get mojibake.
 *
 * If you do not intend to use non-English characters, then use SimpleCapabilityProfile,
 * which has only the default encoding, effectively disabling code page changes.
